SPECIFIGATION forming part of Letters Patent No. 752,488, dated February .16, 1904.

Application led November 23, 1901. Serial No. 83,442. (No model.)

To a/Z'Z whom it may concerns I Be it known that LWHLIAM VroKERY, a subject of the King of Great Britain, residing at 13 St. Anns Villas, Notting Hill, London, England, have `invented certain new and useful Improvements in or Connected with Feed Mechanism for Printing or Like Machines, of whichthe following is a specification.

The obj ect of this invention is improvements in or connected with feed mechanism for print- A ing or like machines, whereby a pile of paper on a raising table is presented at the proper height to a rolleror rollers or-other device on f the end of a lever or levers situate on a shaft for the roller to grip' the paper and. convey the top sheet of the pile onto and over'atilting table, this having been at themoment lowered, and so soon as the top sheet of paper has been drawn onto it by the roller is lifted to raise or free the top sheet from thelpile.

The paper is then passed to a set of rollers by which it is gripped and carried away over. the tilting board down an inclined .board'having driver-rollers to the stops, each sheet in succession being gripped by a device to insure perfect 'side lay, after which ngers press upon the sheet of paper and hold it firmly in the, true position, while the cylinder-.grippers have taken hold of the sheet and the paper removed, when the fingers lift and allow a fresh sheet of paper to pass into place for a fresh operation.

My invention will be understood from the following description, aided bythe accompanying drawings, in which- Figure 1 is an elevation of sufficient of one side of a printing-machine with my invention Fig. 7 isa plan, on an enlarged scale,y of part of my attachmenty for actuating lthe rock-ing. Fig. Sis a plan view ofthe slide, the

table. weighted lever carried thereby, the lingers,

Fig. 6 is a view showing` andthe mechanism for actuating the same.

Fig 9 is a sectional'elevation of the front or entering end of the machine.

g Figs. 10 and 1l are detail views, in side and front elevation,

lrespectively, of the knucklejointed lever.

Fig. 12 is a similar view of a cam and a powertransmitting rod. Figs. 13 and 14 are oppositey side elevations of the parts shown in Fig.

8.l Fig. 15 is an elevation of the said weighted lever and stops for actuating the latter.

,'For the' purpose of my invention I place l sure on the pile of paper and insure the mechanisni bringing the table "up to the proper height for perfect feed.

' Fixed Von the shaft j is an arm m, the free end lof which is supported by a spring a, encircling a rod p, the spring n supporting the arm fm, for adjusting the pressure of the lingers ,k on ,thepile of paper and relieving the parts of the strain and weight of the rod t and arm c. l

The arm t', and consequently the slotted rod faq-ratchet f, andraising table as, are actuated i bya 'amq. on the main shaft r, also carrying a spring-controlled knuckle-jointed arm s or arms constructed as at Figs. 10 and 11, said `arm carrying rollers. t, which as they come round press upon the top of the pile u and draw the top sheet olf onto a tilting table fu for being passed through the feed mechanism.

The tilting table 'u is pivoted to the frame.

work c of the mechanism at fw, and is so situate that when at its lowest 'position-it is just belowthe top of the pile of paper u, as at Fig. 1, and such tilting table lv is connectedvwith a roda, `having a roller y, acted upon by the cam z, for raising by the cam action from the main shaft at the moment the top sheet of the pile has been drawn over it, and this action will lift or free the top sheet from the pile u and allow free movement of same while being drawn olf. The tilting table c is formed in three sections, and the middle is shownasvprov vided with a rubber or other pad 1, onto which the gripping-roller grips the paper, so as to insure perfect action without slip.

Situate just under the tilting table is a shaft 2, carrying lingers 3, which fingers 3 have a motion on each side of the center section, of the tilting table by cam from the main shaft for action upon a sheet or sheets of paper to replace them in the pile should by any means more than one sheet be drawn up by the gripping-rollers. The axle of the lingers 3 is pivoted to the frame c. Said ngers are actuated by a rod 4, having a movement from cam 5, having a race for engaging the pin 6 of the rod 4, which rod is slotted for encircling the main axle r, as shown.

Just at the back of the tilting table fu is arranged a driving-roller 7, and above this roller 7 is situated a set of wheels 8, arranged on knuckle-jointed or other levers 9, affixed to a rod 10, said rod 10 being actuated by a pin 11 v on the cam 5 on the main shaft 1' to raise the wheels 8 to' allow the paper to pass between them and the roller, the wheels 8 loweringto grip the paper between them and the roller`7 for conduct to an inclined board 12, also having driven rollers 13, down which the sheet is carried to the ordinary stops ofthe printingmachine. Just before each sheet arrives at the stops a cam 14 on the main .shaft r fully operates through levers 15 16 or other mechanism a sliding bar 17 situate in the inclined table 12. This bar 17 carries a lever 18, weighted at one end to render it capable of gripping the paper between its gripping-surface and the sliding bar 17, and when the bar 17 has been actuated a suitable stop 19 or other appliance on a rod 19, situate on the inclined table, will act upon the pin 18a on the weighted lever 18 and have lifted the gripping end from the sliding bar 17 to allow of the paper to pass underneath it, and on the return movement of the sliding bar 17 the stop 19 will free itself from the pin 18L and allow the gripping end of the lever 18 to drop and grip the paper, so that by the return movement of the sliding bar 17 the paper will be carried to the side stop 20 and placed in proper position for accurate side lay, and the gripping-surface will by reason of the resistance of side stop 20 slip over the paper, and just as the gripping-lever 18 has reached the end of its working stroke the stop 21 or other ap'- pliance, also on the rod 19a on the inclined table, will act upon the pin 18 and reverse or raise the gripping-surface and release it from the sheet of paper ready for the grippers on the printing-cylinder to take it into the machine in the usual way. rlhe weighted lever previous sheet. ered by any applianceV on the printing-machine, and the fingers 22 are actuated from `the lever 16 during the lowering movement 18 or other device, together with the actuating devices 19 21 on the inclined table, is adjustable to suit sizes of sheets of paper to be printed. A

YVhen-it is desired to feed two sheets at one time for printing, I employ two sets of rollers t, placed side by side, and the bar 17 is formed in two connected portions by suitable rods for a movement to and from each other, each portion being provided with a gripping and stop device to insure the necessary side lay.

When the sheet on the inclined table is in position for the cylinder-grippers, (not shown,)

dropped onto the sheet'of paper to hold it rmly in its proper position until the grippers are just about ready to grip the sheet when the inclined table l2 is raised, and then the grippers take hold of the sheet and draw it through between the table 12 and the nvgers 22, and when the sheet is entirely removed the table 12 lowers and the fingers raise, the next descending sheet falling'into place to be adjusted for side lay, as with the The table is raised and lowof the table by a rod 23, connected also to a plate 24, over which an adjusting-screw 25 of l, the linger-arm 26 rests, so that when the lever 16 is completely moved outward the plate 24 will be moved away for the adjustable screw 25, with the fingers, to fall; but when the table is raised suiiiciently high the plate 24 will return to its normalv position, ready,` for the linger-'arm26 and adjustable screw 25 to restas before. Q Y

In connection with the paper-gripping roller 8 I provide a lever 27 or other appliance, so that on each sheet being moved the rollers t will during the rotary movement of the knuckle-jointed bar s ride againstl the lever 27,

and thereby be shifted a short distance to ex=V i pose a fresh surface for the next sheet.

Having thus described the invention, what.

I claim is#- 1. In feed mechanism for printing and like.
